Aviation

Hi Aditya,
Yes, you can go for it, if you meet the requirements to get into 'Steward course"/
Please note - In aviation industry, male and female are in cabin crew department. The female cabin crew is known as Air Hostess and male Cabin crew is Steward, both have same responsibilities in flight.

As of now, the best autonomous body that provides PGP in Aerospace and Aviation Management is 'Indian Institute of Management, Bangalore'.

Yes, you need personality, good communication skills and good attitude. So, I don't think maths as an optional subject in class 12 will create any problem.

Yes, you can and it is not necessary that your Bachelor's degree should be related to the aviation field. Even after 12th, you can apply for pilot training. For the career as a pilot and the ways to become a pilot, you may refer to the link below:

Dear Jyoti,
To study Aeronautical Engineering, you need to have the below requirements to be eligible for the course. To be an aeronautical engineer one should have a graduate degree (B.E/B.Tech) or at least a Diploma in Aeronautics. The basic eligibility criteria for a BE / B.Tech is 10+2 or equivalent examination, with Physics, Chemistry and Mathematics and must have a fairly high percentage of marks in the aggregate.

Yes, of course, you can take admission without having maths as a subject in class 12th.
